COMBINATION-Loox.

a citizen of the United States, and a resident oi Port onehalf ofthe lock casing. Fig. 4 is a'detail eleva-v Chester, county of Westchester, State of New York, have invented certain new and useful Improvements Vin Combination-Locks, of which the following-'is a full, clear, and exact description.

This invention relates to locks which do not employ the -ordinary key; and the main object of the invention is to provide simple and eiiicient means whereby a lock having a plurality of rotary tumblers are adapted to engage the shackle ofthe lock atboth ends or slianks thereof, and which have characters that by a predetermined arrangement may be `made to register in such a Way that the locking shank' or end of the shackle may be entirely released from the lock casing, which is simple in construction, and which has the casing so made that the combination tumblers will not be in-` jured While in use. y

A-urther object oi lthe invention is to provide means whereby the combination after it has once been set to release the shanks of the shackle will not become disarranged when the shackle has its locking end or shank released from `the casing, and to provide means whereby the shackle may be held in a raised or unlocked position. v

With these and other objects in view, the invention will be hereinafter more particularly described with a part of this specication, and will then be pointed out in the claims at the end of the description.

In the drawings, Figure 1 i`s a perspective view ofl one form of device embodying my invention. Fig. 2 is a vertical section, partly' in elevation, taken on the line II-II oi Fig. 5. Fig. '3 is a detail elevation of tion of the shackle; and Fig. 5 is a fragmentary transverse section taken on the line 5-5 of Fig. 2.

The'casing 10v may be of the usual or of any preferred-form. As shown the casing 10. is made in two parts 1l and 12, arid one olthese'parts, as 11, may have tapering lugs or projections `]3'Which are adapted to tit in corresponding recesses in the other'meinber to properly aline said members when placed together, and said members or parts are provided with openings 14, by which the part-s may be held together by screws or rivets 15. The casing is provided with an opening 16, .one-half ol' which is in each part of the casing, and in said opening is adapted to fit the shank or leg 17 of the shackle 18. Thevleg 17 of the shackle is suitably guided in the casing, epd is providcdwith `a seriesot projcctions'or lugs 19, 20, 21, 22, and 23.

These lugs or projections are properlyspaced 'apart and between the lugs 19, 20, 21, 22, and 23 are spaces in the last three of which a plurality of rotary tumblers 24are adapted to t. These rotary tumblers Specification of Letters Patent.

are normally held in slots 25 in the casing, and each tumbler has .an opening 26 through which'passes the shank 17 of the shackle. Each tumbler has a slot 27 which is adapted' to register with the lugs on the shackle so that when all of the slots 27 are brought into alinemcnt with the lugs on the shackle the latter may be raised through the slots. These tumblers have theusual characters on theiperiphery thereof which are adapted by a predetermined arrangement thereof, to indicate when the slots 27 of the rotary tumblers are in alinement with the lugs oi' the shackle. The shackle 18' has a curved portion 28 and a short leg or shanku 29 which is much shorter than the shank 17, the latter extending substantially the entire depth' of the casing. vThe shank" or locking end 29 of the 6olv shackle is adapted to fit`into a recess or opening 30 in i -may be released from the lock by moving the shackle to the position shown on dotted lines in Fig. 2. The shackle 18 is provided with collars 34 and 35, one on each leg, which are adapted when the shackle is in its inner or locked position to entirely close the openings and form a support for the shackle on the casing.

For the purpose of sustaining the shackle in its outward or unlocked position to permit it to be rotated with the leg 17 as a pivot or axis, and to prevent the disarrangement of the tumblers 24 during the movement of the shackle, I place the lug 19 in suoli a position that it will engage and be limited in its unlocking movement by the shoulder 36 of the casing, and the lug orprojection 23 is made of such length that it will engage all of the tumblers 24 when the shackle is in the position shown in dotted lines in Fig. 2. As will be seen, any movement the shackle with the shank or leg 17 as an axis, after the short end 29 has been released from the casing willl causev the tumblers 24 to rotate with the shackle so that they will not become disarranged when tli'e short end 25 is moved away trom the casing, and the shackle projections may be readily made to pass through the slots of the tumblers when it is desired to place the shackle in a locked position. The rotary movement. of the shackle 18 whenit is in its outward or unlocked position will cause the lugs 19 and 20 to span a projection 37.011 the casing, to sustain the shackle in the unlocked position. This projection 37 extends partly around the opening 16, so that when the lug 19 becomes disengaged therefrom the longer leg or shank 17 of the shacklemay be forcedinto the opening, to cause the short leg or end 29 to enter the f opening 30 of the casing. By shifting the position of the tumblers 24 and 32 the shackle will lbe securely locked within the casing 10.

The shackle as well as the tumblers may be differently constructed and arranged, and there 'may .be any suitable number of the-tumblers, and to protect the tumblers from 4injury while the lock is in use, I enlarge the upper and lower portion of the-lock casing l0 as at 38. This enlarged portion or flange will extend `outward beyond the periphery of the tumblers andwill protect the same, and at the same time the tumblers are so arranged that they may be readily operated at 4any time by hand.

From the foregoing it will be readily seen that a simple and efficient combination lock is provided in whichthe shackle may be held at bothoi its ends or legs, and in which the shackle may have its locking end moved away from the casing and rotated while sustained by 4the casing without disarranging the tumblers.
